  3. 3. Energy Feedback and Demand Response Strategies Exploring Household Engagement and Response Using a Mixed Methods Approach

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Anders Nilsson; KTH.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy feedback; demand response; household energy consumption; energy efficiency and conservation; demand flexibility; smart grids; smart homes; Industriell ekologi; Industrial Ecology;

    Sammanfattning : Real-time energy feedback (EF) and demand response using dynamic pricing tariffs (DR) have been suggested as effective intervention strategies to meet the need for increased energy efficiency and demand flexibility in the residential sector. Although previous studies provide some empirical support for the effectiveness of EF and DR, evaluation approaches used in practical experiments and field trials commonly suffer from several methodological shortcomings, preventing deeper of knowledge on the potential and barriers for EF and DR to influence household energy consumption.

  4. 4. Energy use and environmental impact from hotels on Adriatic Coast in Croatia current status and future possibilities for HVAC systems

    Detta är en avhandling från Stockholm : KTH

    Författare :Vlasta Zanki Alujevic; KTH.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVAC systems; hotels; energy performance; energy efficiency; environmental savings; energy audit; system approach; sustainable energy systems; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik;

    Sammanfattning : This thesis analyses a specific type of energy usage system, “energy usage in hotels”, and how this system behaves. In order to evaluate the current state of energy use in hotels, an energy audit questionnaire was developed and conducted among 31,5% of hotels on the Adriatic coast. LÄS MER

  5. 5. Efficiency Improvements in Waste-to-Energy Combustion Processes Method Development and Evaluation

    Detta är en avhandling från Borås : Högskolan i Borås

    Författare :Eboh Francis Chinweuba; Högskolan i Borås.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid waste; exergy; entropy; higher heating value; improvement potential; waste-to-energy plant; efficiency improvement; cost evaluation; simulation; modelling; Resource Recovery; Resursåtervinning;

    Sammanfattning : is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. LÄS MER
